In [[psychology]] and [[logic]], '''rationalization''' (or making excuses) is an informal [[fallacy]] of [[reasoning]] in which one constructs a logical justification for a [[belief]], [[decision]], [[action]] or lack thereof that was [[originally]] arrived at through a [[different]] mental [[process]]. It is a [[defense]] [[mechanism]] in which perceived controversial [[behaviors]] or [[feelings]] are explained in a [[rational]] or [[logical]] [[manner]] to avoid the true explanation of the behavior or feeling in question.
This [[process]] can be in a range from fully [[conscious]] (e.g. to present an external defense against ridicule from others) to mostly [[subconscious]] (e.g. to create a block against internal feelings of [[guilt]]).
Rationalization is one of the defense mechanisms proposed by [[Sigmund Freud]], which were later developed further by his daughter [[Anna Freud]].
According to the DSM-IV rationalization occurs "when the [[individual]] deals with [[emotional]] [[conflict]] or internal or external [[stress]] by concealing the true [[motivations]] for his or her own [[thoughts]], [[actions]], or [[feelings]] through the elaboration of reassuring or self serving but incorrect explanations."
